Zlatan Ibrahimovic came off the bench to score the winner as holders Manchester United had to work hard to beat Championship strugglers Blackburn in the FA Cup fifth round.
Striker Ibrahimovic was allowed too much time in the box to latch on to fellow substitute Paul Pogba’s pass and tuck in from close range to set up a quarter-final tie against Premier League leaders Chelsea.
Danny Graham had given the hosts the lead with a rising finish following excellent play by Marvin Emnes, who himself had tested Sergio Romero with a thumping effort moments earlier.
In response, Rovers goalkeeper Jason Steele pushed away Ander Herrera’s fierce shot, but Marcus Rashford equalised for the visitors by going round the goalkeeper and slotting in from Henrikh Mkhitaryan’s precise pass.
Rovers striker Anthony Stokes had a goal rightly ruled out offside following Romero’s triple save late on.
